-tains to make and use the same, reference being had to the. accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

In certain classes of machinery it is desirable to revolve a rotatable lbody in one direction for;a time and to then reverse the rotation, as, for instance, in the operation of the washing cylinder of a washing machine.

Our invention relates to gears of tfhis character, and is designed to furnish a mechanism which will automatically convert a continuous rotary motion of a driving shaft into a regularly reversed motion of a driven member. In washing machines in which the clothes are mechanically vrubbed in a revolving cylinder, this reversal of rotation is particularly desirable for the reason that when the cylinder has been revolved for a short time the clothes become packed in the cylinder and thus the eiiiciency of the machine is great-ly dimin-'l ished.

We have, in the speciication, by way of illustration, shown our inve ion as applied to and connected with the rotary cylinder of a washing machine, which cylinder, by means of our inve tion, is aut'- matically caused to rotate f r a short tinie in one direction and to thenrevolve in the opposite direction.

To these ends our invention consists of the devices, construction and arrangement of parts hereinafter described, and shown and illustrated lin the accompanying drawings, in which- Figure l is a vfront elevation of our gear with a portion of the case; in which is mounted broken away; Fig. 2, a vertical -central sectional elevat-ionviof the same seen from 'therightn Fig. 1, and Fig. 8, a

front elevation of a washing machine pro-A vided with our gear. l

Like numerals of reference indicate like parts in all the views. In the drawings, l is a driving shaft provided with a suitable pulley not shown,.and, if desired with a balance wheel. This shaft is journaled in bearings on the machine and at opposite sides of the circular casing 2 which is suitably secured to the front of the machine and incloses the gears hereinafter described. Upon the shaft l is a sleeve 3,

movable longitudinally upon the shaft'but revoluble therewith by reason of a splineand-groove arrangement, such for instance, as pins 4 projecting radially from the shaft into elongated recesses 5 in the sleeve. It will be seen that the pins and recesses cause the sleeve to revolve with the shaftbut per-l mit a limited longitudinal movement of the sleeve upon the shaft. At each end of the sleeve and rigid therewith is a clutch-member 6 4adapted to engage a corresponding clutch-member 7 rigidly connected with or forming part of beveled pinions 8 loose upon theshaft 1. It will be seen that as the sleeve is moved-longitudinally the members vof one or the other of the clutches will be operatively connected according to the direction in which the sleeve is shifted. This movement at regular intervals of the sleeve in one direction and then in the other, direction, is accomplished by means of the devices now to4 be described.

9 is a'shaft rigidly connected at one end with the cylinder 10 to be rotated, and at its other end rigidly and centrally connected with a dish shaped gear-wheel 11, the beveled teeth of which are in mesh with `both the pinions 8. Upon the face of the gear 11 next to the sleeve 3 is aV spiral groove 12 extending from near its center to near the rim of the gear, the bottom of the groove at each end sloping outwardly. This groove is engaged by a pin 18 prgiecting from one end of a lever 14,fulcrunied as at 15, upon a brace or support.16 bolted or otherwise rigidly secured to the inside of the casing Vas at 19, with a lever 20. This lever is fulcrumed at'its lower end, asl at 21, upon the brace 16.' The lever 2O is recessed near its lower end, as at 22, to receive loosely the lower end of a lever23, fulcrumed, as at 24, upon the brace 16., The upper end of this lever is lnotched as at 25, the notch being engaged with a rib or ring 26 which encircles and is rigid with the sleeve 3 at its middle.

27 is a weight carried by the lever 20. In the present construction, for illustration, the weight is'pivotally suspended from the lever near its upper. end, as at 28, and has a recess in its side to receive the lever the sides of they recess forming stops which limit the swing of the weight upon its pivotal support. It will be seen that the driving shaft being'in motion and one of the clutches 6-7 being engaged, the gear 11 will be revolved andthe pin 13 will traverse the spiral groove 12 to the right or to the left, depending upon the direction in which the gear 11 is rotated. The lever 14 bein@ thus caused to swing upon its pivot the link 18 is moved until the end 'of its slot engages the pivot-pin 19 on the lever 20. This lever is now, just before v the pin 13 lreaches the end of the spiral grooves, pulled or pushed,as the case'may be, into upright position and is then by force of the weight 27 caused to swing upon its pivot to the limit of its throw. The recess 22 in the lower end of lever 20, being engaged with the lower end of the lever 23, by its throw and the impact of weight 27 causes the upper end of the lever 23A to quickly slide the sleeve 3 outof engagement with one clutch and into engagement with the other clutch, which now, through its pinion 8, imparts a reversed rotation to the gear 11 and to its attached cylinder 10. If by any means the reversing gear fails to act, the pin 13, through the wedge-like action of the inclined floor of the spiral groove at its ends, emerges from the groove and now rides upon the annular ungrooved portion of the plate. To prevent the pin 13 from rentering the spiral groove at the end of its course before the completion of the shifting of the sleeve and the reversal of the rotation of the gear 11, the lever 14 is provided at its lower end with a laterally projecting weight liliL whichl holds the upper end of the lever andthe pin away from premature en gagement with any neighboring convolution of the groove.

29 is a hand-lever fulcrumed, as at 30, in the case 1 and having a notch 31 positioned and adapted to receive thering 25 when the sleeve 3 is central between the two pinions 8 and when both clutches are disengaged. A set-screw 32 4serves to hold the.hand-lever elevated and out of engagement with the sleeve 2 when the machine is in operation. By moving the lever into engagement with the ring 25 'the driving shaft may continue to run without imparting any movement to the gear 11.
